Crucial p5 ssd3/6/2023 ![]() We also monitor cache recovery via multiple idle rounds.Īs per the norm with Crucial, the P5 Plus takes advantage of the company’s dynamic write acceleration algorithm, which enables its fast write speeds, but once the SLC write cache is saturated, write speeds will degrade below that of rated levels. ![]() We use iometer to hammer the SSD with sequential writes for 15 minutes to measure both the size of the write cache and performance after the cache is saturated. Sustained write speeds can suffer tremendously once the workload spills outside of the cache and into the "native" TLC or QLC flash. Most SSDs implement a write cache, which is a fast area of (usually) pseudo-SLC programmed flash that absorbs incoming data. Official write specifications are only part of the performance picture. Sustained Write Performance and Cache Recovery ![]() Once we turned up the heat and hammered it with high queue depth workloads, peak random performance results were well ahead of most Gen3 SSDs, as well as the Sabrent in reads, but still lagged both the WD_Black SN850 and Samsung 980 Pro. In terms of write performance, however, it lagged behind the WD and Sabrent by a fair margin.įurthermore, Crucial’s P5 Plus showed somewhat weak random IOPS performance in comparison to the other Gen4 competitors in Crystal Disk Mark, lagging even the PCIe 3.0 x4-based SK hynix Gold P31 by a few thousand IOPS at a QD of 1. The results from ATTO show the P5 Plus’s performance ramping wasn’t as consistent as its competitors across various block sizes, but it did trade blows with both the WD_Black SN850 and Samsung 980 Pro.
